feat(network-policies): CiliumCIDRGroup per client network

One group per UDM client network (ULA + IPv4; ISP-delegated GUA prefixes are not stable and are left out), so LoadBalancer CNPs can restrict sources via fromCIDRSet.cidrGroupRef instead of repeating subnets. Adds no policy; no traffic changes. Refs S28-19 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
